DIVISION-BLOCK FOR HAY-BALERS.

Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed October 23, 1905. Serial No. 283,923.

To all whom, it may concern.-

' Be it known that I, JULIAN H. PITKIN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Division-Blocks for Hay-Balers, of which the following is a complete specification.

This invention relates to division-blocks for balers and it consists incertain improvements therein designed to better protect the engagingedges of the block from the severe usage which it generally receivesfrom the retaining springs. The transversely extending grooves areeffectually prevented from becoming injured and choked with hay at theirends, thus rendering easy the passing ofthe wires therethrough, and alarge welldefined recess is provided to actuate the trigger on theblock-alarm mechanism.

Referring to the accompanying drawings, Figure 1 represents an elevationof a divisionblock in which is embodied my invention, and Fig. 2 is anelevation of an edge thereof. Fig. 3 shows a perspective, on a reducedscale, of the block illustrated in the preceding figures. Fig. 4represents an enlarged perspective of one of the reinforcingplates,having formed integral therewith a recess for operating the trigger ofthe block-alarm; and Fig. 5 is a similar perspective of suchreinforcing-plate without the recessed portion formed thereon.

In the drawings, 1 designatesthe vertically-extending center board, and2 the side boards. Between the adjacent edges of the side boards areformed the oppositelydisposed transverselyextending grooves 3, throughwhich the wires are made to pass in threading the machine, preferablythree of these grooves being formed on each side of the block. Toprotect the ends of the side boards adjacent to the grooves from thebruising effect of the retaining-springs of the baler and to insure anormal sized opening at the ends of said grooves, the reinforcingplates4 are mortised into the edges of the block. These plates correspond inwidth with the thickness of the block and have depth and lengthsuflicient to give them ample strength. In the sides of thereinforcing-plates are formed the notches 3, which register with thetransversely extending grooves 3 and correspond therewltn 1ncrosssection. On the inner face of each plate is' formed thevertically-extending grooves 5, adapted to receive the edge of thecenter board 1. The said plates are preferably secured in place by meansof screws received by the apertures 6.

On the upper end of one set of the reinforcing-plates and formedintegral therewith are the large recesses 7, the walls of which are madeflush with the sides of the block. The function of this recess is toengage and actuate the trigger of the block-alarm. Heretofore in suchdevices the openings of the grooves through which the wires are threadedwere depended upon to actuate the alarmtrigger, but owing to its smallsize they would often become clogged with hay and the alarm mechanismthereby rendered inoperative. With a large and independent recess theoperation of the alarm mechanism is rendered more positive andefiicient.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A division-block for hay-balers consist ing of a center board havingside boards secured thereto, with transversely-extending grooves betweensaid side boards and reinforcing-plates arranged flush with the edge ofsaid block, said reinforcing-plates having vertically-extending grooveswhich receive the edges of said center board, and trans verselyextendingnotches which register with the grooves formed between said side boards,substantially as and for the purpose specified.

2. A division-block for hay-balers provided with transversely-extendinggrooves and having reinforcing-plates arranged flush with the edges ofsaid block, said reinforcing-plates having notches therein registeringwith the said grooves, and a recess formed above the said notches,substantially as and for the purpose specified.
